I just installed the 64-bit Linux: analysis2.2.2_linux64r4.tgz I tried to run the tutorial: Analysis Beginners' Course CCPN project CcpnCourse1a When I tried to open the project CCPN project CcpnCourse1a I got the error message: no module named downgrade.v_2_0_b3 If I call the help widget, I got: The specified file or folder /usr/local/ccpnmr/ccpnmr2.0/doc/ccpnmr/analysis/OpenProjectPopup.html does not exist. that is indeed true. What shall I do? Thank you in advance Christian
